. Figure 2 is a perspective view of one of the "slats,

with the spiral springs attached.

Similar letters 'of reference' indicate corresponding parts in the several figures;

The nature of my invention consists' in aV guide,r

which supports the spring without theaid 'of' a' disk. The object of theinvention is to obtain a portable `top, which can he easily removed, that'the center 4slats vmay be readiiyshifted to the foot of the bed when they become compressed by wear; also, to obtain o guide, byrnennsf of which each spring is perfectly supported without the aid of cords or any-other m'a-v teriai running from one spring to the other.

To enable others skilled in the art to understand and constructmy invention, I will proceed'to describe it.' l

having an eye at `the upper end, into which is fastened a wire or cord of any material vsufieently strong to iig. 2.' -The lower end Vof the guidepasses through tion, permitting it to passdownward when the spring iscompressed. The wireor cord used to retain the guide in the center of the spring 'may be fastenedv in any convenient manner to opposite sides of the same. Having thus described the nature and object of my invention,

What I claim as new, and 'desire l,Letters Patent, is

' The combination of the guide E, th'e point passing thronghthe slat and the top, with an eye held by n in the manner and for thepurposes described.
